I wonder if one workaround isn’t to store info like 1Password key and password - not username - in a pdf with a simple, easily remembered password, in an email IMAP account with a similarly easy password? Could even be a bitly link to a Dropbox file. I know that creates a huge security hole but it’s only one if someone else is able to identify which account it applies to.
